Application med August 1, 1912. serial No. 71t,830.

.To aZZw/tomf it may concern.'v y Be it known that I, CHARLES a citizen of the United States, Auburn c ofl New York, have invented certain new and useful Improvements in Disk Harrows, ofV which the following is a specification.

My invention relates to disk harrows havpivoted gangs, thatmay be operated at varylng angles relative to the line of draft by being turned about a vertical axis connecting the gang frames with the draft frame, the gang frames being also permitted about horizontal axes arranged in a fore and aft direction, and consists 1n means for applying spring pressure between the draft frame and the inner ends of the gan and means for adjustably controlling a r1s ing and falling movement of the inner ends of the ang framesfrelative to the draft frame; t provide. a construction simple in its parts, durable and efficient in operation. I attain these objects by means ofv mechanism, one embodiment of which is illustrated in the accompanying drawings, in Which- Figure 1 represents a top plan view of a invention "forming S. SHARP,

a part thereof; l

fFig. 2 is a rear elevation of Fig. 1 on an enlarged scale; c

Fig. 3 -is an end elevation of'a harrow, partly in section, and designed to illustrate the operation of the invention; y

Fig. 4; is a detached sectional elevation of part of the structure designed only to illustrate the construction an operation of the spring pressure mechanism;

Fig. 5 is a rear elevation of Fig. 4'

residinsg atin the county of Cayuga a d tate llke parts throughout vand having th manner of mounting the adjustable stop members.

The same reference characters designate the several views.

r lThe draft frame of the machine includes a U-shaped member l, having a transverse frame member 2 secured to the rear ends of therside'members thereof, and 3 represents longitudinally arranged bars spaced apart e rear ends thereof secured to the middle portion of the frame member 2,

e object of my invention being to f the bars are j rig. e is a detached dean of the struc ture designed to illustrate the manner of mounting the spring pressure bar' upon the draft frame;

Fig. 7 is a ortion of the draftlframe of a harrow and esigned to illustrate a part of the pressure mechanism; Fig. 8 is an end elevation of Fig. 7, partly in section;

Fig. 9 is a plan viewof one of the parts of the pressure controlling mechanism; l Fig. lOis a side elevation of Fi 9; and Fig. 11 is a detached .detailo` the pressure mechanism, designed to illustrate the gan and the front ends 'to the middle portion of the U-shaped Amember l, and extendingA in front thereof for the purpose of receiving a draft tongue or other draft devices.

The gang frames include head members 4 having'depending standards secured thereto, the lower ends of the standards bein secured to bearing boxes 6, in which are Journaled the ang axles 7, including spacing spool mem ers 8 form mounted thereon. The ang frames are connected with the -draf frame by means of vertically arranged bars 10, having forwardly turned portions 11 at their lower ends disposed in a horizontal plane and received by openingsin ear members l2 integral with t he outside bearin box 6 in a manner permitting the gang frame to turn about the axes thereof. The upper ends of ournaled in vertically arranged sleeve members 13 integral with bracket members 14 that are secured to opiposite `ends of the transverse member 2 of the draft frame in a manner permitting the frames to turn about the vertical axes of t e bars 10' and at varying angles relative to the line of draft.

and disks 9 of a commonv 15 represents draft links having the front ends' thereof pivotally connected with the side members of the draft frame and inclining downward and rearward. These links are provided with hook members l'at the opposite ends thereof whereby the same are fiexibly connected with the outside bearing box 6. 17 represents hand levers pivotally mounted upon the draft frame members 3 and having a common form of spring-l pressed sliding detent mechanism mounted thereon and adapted to engage with notched' sectors 18 secured to the frame members and arranged concentric to the' axes-f'lf'thc levers, the lower ends of the hand levers the pressure lever 32. 39 represents a combeing connected, bv means of links 19, with the inside bearing box 6 of the oppositely disposed gang frames, and by means of bars 20 with the inner ends of the head members 4 of the gang frames in a manner permitting the operator to control the angle of the disk gangs relative to the line of draft. 21 representa supplemental draft links having the .front ends thereof pivotally connected with the side members of the draft frame and their rear ends with the head members 4 of the gang frames. 22 represents guide blocks having openings 23 at the lower ends thereof that receive vsecuring bolts 24 that are received by openings through the lower portion of the vertical web of the frame member 2, and pintle members 25 at the upper ends thereof that are received by openings in the upper portions of said vertical web, the guide blocks having rectangular portions 26 that are corrugated transversely in a' manner to receive stop members 27 that are corrugated in a like manner, and permitting the stop meml bersv to be adjusted vertically and be secured in any desired position of adjustment by means of the securing bolts 24. 28 represents a vertical sliding pressure member or bracket having vertically arranged slots 29 at opposite ends thereof that receive the oval shaped boss members 30 that form part of the guide blocks 22 in a manner permitting the pressure member 28 to move freely thereon. Member 28 is also provided with a horizontally arranged slot 31 that loosely receives the rear end of a pressure lever 32 that is pivotally connected intermediate the ends thereof with the lower end of a U- shaped bracket member 33 by means of a clip member 34 secured to the lever, and a pivot pin 35 connecting the clip with the U-shaped member, the U-shaped member being secured to the draft frame bars 3. 36 represents a pressure controlling hand lever pivotally connectedwith a bracket member 37 secured to' the draft frame, and 38 represents a link having the upper end thereof pivotally connected with the hand lever 36 and the body portion thereofslidably received by an opening in the opposite end of pression spring encircling the lower end of link 38 and operative betweenan adjusting nut 40 and the lever 32 in a manner to yieldingly turn said lever about the axis thereof in a direction to cause 'the rear end thereof to press downward upon the pressure member 28. 4l represents a toothed plate secured to one of the draft frame members 3, and 42 a foot controlled dog pivotally connected with the hand lever 36, preferablv co- `axially with the link 38, having the lower end thereof adapted to engage with the toothed plate 41, and the upper end turned laterally, whereby the operator may control the position of the lever. The bars 20 extend in rear of the pivotal connection thereof with the head members 4 of the gang frames and are provided with reinforcement members 43 that slidably engage with the member 28 when the gang frames are adjusted angularly and contact therewith in a manner to limit an upward movement of the inner ends of the disk gangs about the horizontal axes thereof, the stop members 27 being adjustable upon the draft frame in a manner permitting more or less vertical movement o`f the sliding member 28 and of the inner ends of the disk gangs. The force of the spring 39 is operative 'through the lever 32 and the sliding pressure member 28 to yieldingly force the inner disks of the gangs into the soil, and the gangs may be held in substantially a rigid position by means of the member 28 and the adjustable stop 27 which coperate therewith and act to limit the upward movement of the same.

It is to be noted that in this construction the gangs are normally under the pressure of the spring 39, which acts through the member 32 and the pressure member 28. It is also to be noted that the pressure may be varied at any time by adjustment of the lever 36 and that the upward limit of movement of the pressure member may be regulated as desired by simply adjusting the stops 27, the pressure member always being freely slidable along the boss members 30 on the blocks 22 within the limits established by the stops 27 and 'the slots 29 formed in the pressure member. As pointed out above, the vertical movement of the gang frames may also be entirely eliminated by adjusting the stops 27 to such a position that the member 28 may not move upward.

While I have in this application specilically described one embodiment which my invention may assume in practice, it is, of

course, to be understood that the same may be embodied in other forms and that the form shown herein may be modified without dearl'tin from the spirit of the invention. at claim as being my invention, and desire to secure by Letters Patent, is:
